    u can use a psone with ease but to make the old psx mainboard work on 12v is just too much work.(1000,5000,7000 and 9000 series)
    a ps2 is easy, just take out the original power suplly and put plus and minus 12v on the outer pins that go to the mainboard.
    time for the sig:

    yeah, i realize that it is going to be a litttle tough, but hey, isnt that part of the fun of doing it yourself. like i mentioned before, i COULD just buy an invertor, but this has become more of a personal challenge to myself. plus, the old psx that i have is just sitting around now, and i think i would learn a lot if i could make this work.

    buying a ps1, with the car adapter and screen would cost over $200, making a 12v power supply will cost maybe $50, plus i already have an extra screen laying around, so i might as well try. oh, and im not about to trash my ps2 if something goes wrong with the power supply... i will keep you all informed as i make some progress.

    the circuit shouldnt really be too difficult

    somthing similar to a sproggy using a MAX788 for the 3.3v and a MAX724 for the 7.5

    u'll really need to know the current usage before building tho so u know how many IC's u will need in paralell

    if u are lucky it will be under 5A for both rails and u could simply use one of each
